Candice spent 5 1/4 hours doing her homework. Her brother, Ronald, spent 1/2 that number of hours doing his homework. How many h

Elden [556K]

Let

x-----> the number of hours that Candice spent doing her homework

y-----> the number of hours that Ronald spent doing his homework

we know that

$x=5\frac{1}{4}\ hours$

convert mixed number to an improper fraction

$5\frac{1}{4}\ hours=\frac{5*4+1}{4}= \frac{21}{4}\ hours$

$x=\frac{21}{4}\ hours$ -------> equation A

$y=\frac{1}{2}x$ ------> equation B

Substitute equation A in equation B

$y=\frac{1}{2}*\frac{21}{4}=\frac{21}{8}\ hours$

convert an improper fraction to a mixed number

$\frac{21}{8}\ hours=2.625=2+0.625=2+\frac{5}{8}=2\frac{5}{8}\ hours$

therefore

<u>the answer is the option B</u>

$2\frac{5}{8}\ hours$

What is the formula for lineal equetion

Gwar [14]

Answer:

y=mx+c

Step-by-step explanation:

A linear equation means the equation of straight line.

The formula for equation of straight line in slope intercept form is y=mx+c

where, m is the slope of line and c is the y intercept

The formula for equation of straight line in double intercept form is x/a+y/b=1

The formula for equation of straight line in normal form is xcos α + y cos α=p

There are more formulas bur assuming you are asking for the general representation of the straight-line equation, it is y=mx+c.
